    Native Plants for Your Backyard

    U.S. Fish & Wildlife Service Native Plants for Your Backyard Native plants of the Southeastern United States are more diverse in number and kind than in most other countries, prized for their beauty worldwide. Our native plants are an integral part of a healthy ecosystem, providing the energy that sustains our forests and wildlife, including important pollinators and migratory birds. By “growing native” you can help support native wildlife. This helps sustain the natural connections that have developed between plants and animals over thousands of years. Consider turning your lawn into a native garden. You’ll help the local environment and often use less water and spend less time and money maintaining your yard if the plants are properly planted. The plants listed are appealing to many species of wildlife and will look attractive in your yard. To maximize your success with these plants, match the right plants with the right site conditions (soil, pH, sun, and moisture). Check out the resources on the back of this factsheet for assistance or contact your local extension office for soil testing and more information about these plants.

Abstract Goldenseal (Hydrastis canadensis L.) is a well-known perennial herb indigenous to forested areas in eastern North America. Owing to conservation concerns including wild harvesting for medicinal markets, habitat loss and degradation, and an overall patchy and often inexplicable absence in many regions, there is a need to better understand habitat factors that help determine the presence and distribution of goldenseal populations. In this study, flora and edaphic factors associated with goldenseal populations throughout Pennsylvania—a state near the northern edge of its range—were documented and analyzed to identify habitat indicators and provide possible in situ stewardship and farming (especially forest-based farming) guidance.

Wood features ofthe family have been summarized by Metcalfe and Chalk (1950); various authors have mentioned one or more traits in studies dealing with Calycanthaceae (e.g., Wilson 1979) or other families (e.g., Garratt 1934). In view of recent interest in Idiospermum australiense (Diels) Blake, a new comparative study is needed. One goal of the present study is clarification of relationships of Idiospermum to Calycanthus and Chimonanthus. Wood anatomy of Idiospermum was described by Blake ( 1972) and Wilson ( 1979); a new description is offered here to provide more quantitative data. De­ scriptions of the wood of Calycanthus and Chimonanthus provided here incorporate such quantitative data, but also modify earlier descriptions with respect to some important qualitative features. Material of the recently de­ scribed genus Sinocalycanthus (Cheng and Chan 1964) was not available, although the description of that genus suggests it is not strongly different from Calycanthus or Chimonanthus. The present study incorporates material of Calycanthus floridus L. var. floridus, C.

  • Eastern North American Plants in Cultivation

    Eastern North American Plants in Cultivation

    Eastern North American Plants in Cultivation Many indigenous North American plants are in cultivation, but many equally worthy ones are seldom grown. It often ap- pears that familiar native plants are taken for granted, while more exotic ones - those with the glamor of coming from some- where else - are more commonly cultivated. Perhaps this is what happens everywhere, but perhaps this attitude is a hand- me-down from the time when immigrants to the New World brought with them plants that tied them to the Old. At any rate, in the eastern United States some of the most commonly culti- vated plants are exotic species such as Forsythia species and hy- brids, various species of Ligustrum, Syringa vulgaris, Ilex cre- nata, Magnolia X soulangiana, Malus species and hybrids, Acer platanoides, Asiatic rhododendrons (both evergreen and decidu- ous) and their hybrids, Berberis thunbergii, Abelia X grandi- flora, Vinca minor, and Pachysandra procumbens, to mention only a few examples. This is not to imply, however, that there are few indigenous plants that have "made the grade," horticulturally speaking, for there are many obvious successes. Some plants, such as Cornus florida, have been adopted immediately and widely, but others, such as Phlox stolonifera ’Blue Ridge’ have had to re- ceive an award in Europe before drawing the attention they de- serve here, much as American singers used to have to acquire a foreign reputation before being accepted as worthwhile artists. Examples among the widely grown eastern American trees are Tsuga canadensis; Thuja occidentalis; Pinus strobus (and other species); Quercus rubra, Q. palustris, and Q.

    10 JOURNAL OF THE LEPIDOPTERISTS' SOCIETY SPICEBUSH, LlNDERA BENZOIN, A LITTLE KNOWN FOODPLANT OF PAPILlO GLAUCUS (PAPILIONIDAE) J. MARK SCRIBER, ROBERT C. LEDERHOUSE, AND LORRAINE CONTARDO Department of Entomology, Cornell University, Ithaca, New York 14850 Papilio glaucus L., the eastern tiger swallowtail, is one of the most polyphagous of all Papilionidae, yet documented records of it utilizing lauraceous foodplants are rare. Teitz (1954, 1972) is the only author who reports Lindera benzoin (L.), but we have been unable to locate any such original record from the references he listed. Sassafras albidum ( Nutt.) also is recorded by Edwards (1884), French (1885), Scudder (1889) and Teitz (1954, 1972). These authors have apparently cited either Stauffer (1862) or personal communication of John Akhurst. The larval description (" .... the larva of turnus (which was taken from Sassafras) was pea-green above with a yellow edging, beneath purplish­ brown.") suggests that Stauffer's record is based on a mistaken P. troilus larva. Akhurst records a P. glaucus female ovipositing on Sassafras branches while confined in a box. Five freshly hatched first instal' Papilio glaucus larvae were discovered on leaves of spicebush, Lindera benzoin of the Lauraceae, on Snyder Hill near Thomas Road, Town of Caroline, Tompkins County, New York.

In addition to the P. glaucus larvae found on June 25, 1973, another fertile egg was dis­ covered on July 11. For comparisons with growth rates on other food­ plants (Scriber, in prep.), field growth rates of larvae were observed on spicebush until they reached the late stages of the final instal'.

    New York State Stormwater Managment Design Manual

    Appendix H: Landscaping Guidance/Plant Lists H.1 Ponds and Wetlands For areas that are to be planted within a stormwater pond, it is necessary to determine what type of hydrologic zones will be created within the pond. The following six zones describe the different conditions encountered in stormwater management facilities. Every facility does not necessarily reflect all of these zones. The hydrologic zones designate the degree of tolerance the plant exhibits to differing degrees of inundation by water. Table H.5 at the end of this appendix designates appropriate zones for each plant. There may be other zones listed outside of these brackets. The plant materials may occur within these zones, but are not typically found in them. Plants suited for specific hydrologic conditions may perish when those conditions change, exposing the soil, and therefore, increasing the chance for erosion. Each zone has its own set of plant selection criteria based on the hydrology of the zone, the stormwater functions required of the plant and the desired landscape effect. The hydrologic zones are as follows: Table H.1 Hydrologic Zones Zone # Zone Description Hydrologic Conditions Zone 1 Deep Water Pool 1-6 feet deep Permanent Pool Zone 2 Shallow Water Bench 6 inches to 1 foot deep Zone 3 Shoreline Fringe Regularly inundated Zone 4 Riparian Fringe Periodically inundated Zone 5 Floodplain Terrace Infrequently inundated Zone 6 Upland Slopes Seldom or never inundated Zone 1: Deep Water Area (1- 6 Feet) Ponds and wetlands both have deep pool areas that comprise Zone 1. These pools range from one to six feet in depth, and are best colonized by submergent plants, if at all.
